Trouble booting up...HELP!

I have had problems booting up on my laptop for several weeks now. It started where sometimes the Toshiba screen would come up, and then the laptop would never finish booting. Sometimes it would go through fine, and then I could do what I wanted. Sometimes, though, it would go through and end up freezing and I'd have to shut the power off.
Well, the other day it started getting stuck on the Windows screen. I let it go for awhile thinking it might eventually work, but then it went to a black screen that told me I needed to hit control+alt+delete. I did, and that same screen came up. I then restarted my laptop, and now it goes directly to that black screen with the control+alt+delete message.
What has happened, and is there a way to fix it?

Hi, Michelle. Welcome to Apple Discussions.
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk drive.
This is an alternative to repairing the hard drive from the Install disc, and should correct things if an error on the hard drive is the cause of the problem.
Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility. Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). Repair permissions on it.
See if a little hard drive maintenance helps things out.
To attempt to get the iBook to force-boot into OS 9, you can press Command-Option-Shift-Delete while starting up. This instructs the iBook to skip the last boot OS instruction which is saved in PRAM and seek another startup disk from which to boot.
Good luck. Please let us know how things go.

Trouble Booting to Ubuntu Live USB on T440

Hey,
I am having trouble booting to a Ubuntu Live USB on my T440. I turn on the laptop, press enter to interrupt the normal boot, and press F12 to select another boot option. But after selecting the appropritate USB, the screen goes black for a couple of seconds and then returns to the boot selection. It will not boot from the Ubuntu USB, only to the preinstalled Windows 8.
Other guides have recommended disabling Secure Boot (I have done this, it has not worked); others suggest enabling Secure Boot but changing to Legacy Boot (this didn't work for me either).
Once I can successfully boot to the USB, I will be installing Ubuntu, replacing Windows all together. I don't need help with that; just getting the computer to boot from the USB would be great.
Thanks.
Solved!
Go to Solution.

Fixed. My boot USB was made with Ubuntu's Startup Disk Creator (on my other Ubuntu system). On a hunch, I made another boot USB using Linux Pen Drive on the Windows 8 machine. That one worked. I presume it was related to the format of the USB (the working one being FAT32).
So if anyone wants to easily install a Linux distibution on a T440, make your boot USB on a Windows machine.

Fresh OS X install: Trouble booting, crashing.

Hey Apple Community,
I have an iMac 7,1 - mid 2007, 24 inch. About a week ago my iMac (gradually) became very slow, and crashed regularly. Trouble booting as well (booting took ages, with the grey progress bar on the white screen) At that time I was running Mountain Lion.
To fix the problem, I did a fresh install of Snow Leopard, and upgraded to Mavericks.
After this there was still trouble booting, sometimes just a white screen, or a white screen with an apple logo. About one out of five startups are succesful and get me into Mac OS X successfully. (Disconnecting all peripherals gives me a higher success rate.)
When OS X has booted successfully, my iMac is extremely fast, except at some point it just freezes, I just get the round rainbow cursor, and the only way out is a hard reset with the power button.
Since the problem started, there's a process called "kernel_task" that is always using the most memory of all processes (about 400 mb), at all times. However, my RAM or CPU isn't using the maximum capacity, and I have plenty free CPU or RAM.
My system specs:

Macbook late '08 freezing up, has trouble booting after iLife install.

A couple of days ago I installed iLife '11 on my Macbook and went to run the updates that the App Store was telling me were available, including the Mountain Lion 10.8.4 update. I shut the lid of my computer while they were downloading, without thinking and when I opened it again, the screen was dark, but the computer was on. I forced a shutdown and went to reboot but got stuck at the grey Apple logo and timer wheel. I zapped the PRAM and it booted right up but it told me that I needed to restart to install the updates. I did so and had trouble booting again. I had to do the PRAM thing a couple more times to get it to boot but when it did, the only update that installed was GarageBand. I ran it until all of the updates had downloaded and it asked me to restart. Everything went smoothly this time but when I logged back in the OS X 10.8.4 update was sitting there waiting to be installed again. I reset to install twice more but it never installed. Now whenever I'm running an application it will freeze up after a time, and when I go to quit the application the whole computer freezes, forcing me to force shutdown but putting me back to where it freezes on boot up. Freezes when I try to boot into safe mode or recovery mode often as well. I can manage to get in every once in awhile, after zapping the PRAM two or three times, but even that is starting to freeze too. Any one know what's going on? I ran iAntiVirus and it found nothing, I'm working on uninstalling iLife to see if that helps too.
I'm running Mountain Lion on a brand new Toshiba 1tb external drive connected to a Late 2008 aluminum unibody MacBook that I bought off my friend's dad back in March. No internal drive because the one that was in it failed in May.

Let me start by saying do you know how easy it is to replace the hard drive in that MacBook? http://www.ifixit.com/Guide/MacBook+Unibody+Model+A1278+Hard+Drive+Replacement/8 16/1
First thought is to dump the anti virus software. It sounds to me as though your installation of OS X is hosed due to an incomplete update attempt. You need to repair the hard drive using Disk Utility and reinstall Mountian Lion completely, not just the update to 10.8.4.

Trouble booting from Leopard installation DVD

I'm having some trouble booting from the Leopard installation DVD, I was wondering if anyone here could help.
I want to reset my administrator password since OS X does not seem to be accepting it, and I heard that the best way to do this would be to boot from a Mac OS X installation DVD or CD and change some settings. When I start up my computer with the Leopard DVD in the drive, I hold down the 'C' key after the chime, and continue to hold it until the spinning gear appears.
From there, the spinning gear stays on the screen, and nothing happens. I've heard that it takes a while for the screen to come up, but I let it sit for over three hours and nothing happened. I also tried holding the Option key at startup and selecting the DVD, but the same thing happened. The DVD is in good shape and has no deep scratches, and it appears right away in the OS itself. I can't access the installer from the OS since it asks for my Administrator password, which it does not seem to be accepting. I also tried another solution to the Administrator password problem that involved typing some commands in Single User mode, but that did not help either.
Any help would be greatly appreciated.

what exactly did you try to do in single user mode?

Windows XP SP2 freezes and then has trouble booting up

I've got a recent problem with my PC freezing while in use. All of a sudden it freezes with no error messages. The only resolution is to reboot the PC; however, most times the PC has trouble booting up after that. Usually at some point before it boots up I'll get a CMS checksum error, hit the F1 key to continue and Windows will load up. I'll have to restart it multiple times before I can get it to boot or I have to unplug the PC, let it sit overnight and then it tends to boot up with no problems the next morning.
I did notice that the fan to the PSU isn't running all the time. Should it be? I would have thought so, but don't know for sure.
I haven't tried reloading Windows over the current installation. I have an original Win XP disk ()non-SP2). This is a Windows CD, not a restore CD. I've updated to SP2. Will it be OK to reinstall over it with an older version of XP? I guess I can just not replace any newer files if it asks?
Thanks for any feedback.

Bosskiller, I just know the basics of hardware installation and such. I can put them together, but don't have much knowledge in diagnostics. The Geek Squad ran the basic diagnostic package and said everything checked out OK and that it was most likely a mobo or processor going bad.
I see you linked to an earlier post you made. However, if the memory checked out OK and it's run fine for the last 6 months without any problems, would it do any good to run another memory check on it?
"Bosskiller, I just know the basics of hardware installation and such. I can put them together, but don't have much knowledge in diagnostics. The Geek Squad ran the basic diagnostic package and said everything checked out OK and that it was most likely a mobo or processor going bad."
suggest you to ignore "The Geek Squad ran the basic diagnostic package" and to test it personally.
get memtest http://www.memtest.org/download/1.70/memtest86+-1.70.floppy.zip
extract files and make diskette bootable from installer. then reboot PC and boot from floppy, select test n5 only from there and leave it to test over 20times ensure no errors will come... step by step with memtest: https://forum-en.msi.com/index.php?topic=103598.msg760534#msg760534
other way is to try to install XP with each memory sticks separately until works.. leave only one stick into DIMM slot close to CPU socket and have a try to install OS again, if no go remove memory and replace it with other one. and retry.
or take PC to some computer repair shop to diagnose.

My Windows 2000 machine has trouble booting up after instaling PCI-6503 card

After I installed the card in my Dell Desktop has trouble booting up. I have to pull the power cable out and then reconnect for it to come up.

Hello;
The best way to go about that is to completely uninstall the NI-DAQ driver you have installed on that machine, turn the computer of and remove the board from it.
You then reintall NI-DAQ, and put the board back. If the same behavior shows, the best bet is to search for some other peace of Software/Hardware currently installed on the machine that might be conflictant with NI-DAQ.

TROUBLE BOOTING MAC OS 10.3.2

I am having trouble booting my powerbook g3 pismo to the mac os. when i start it up, it has the apple logo, then after about 3 seconds it goes to a circle with a line through the middle!!! what are possible causes for this?? How can i fix this?? thanks -roger

roger,
"well when i bought it last week it had 10.3.2 on it..."
How do you know that?
"It did not come with any install disks or system disks however,..."
Can you contact the seller, and request that they be provided?
"I have an OS 10.2 install disk which I previously purchased."
Do they look like THESE?
If the Firmware Update, was not applied, prior to the installation of OS X, there could be problems.
As you really don't know the condition of the system, it's difficult to diagnose where the problem lies.

Trouble booting iBook

I'm having problems similar to those many people are having on here: my iBook recently started having trouble booting up. When I try, I get the chimes, but after that nothing happens; there's just a blank dark screen. The whirring noise that usually accompanies start-up is noticeably absent. So far, if I let it sit, off, for anywhere between 10 - 30 minutes it does eventually start up, but I know it'll only get worse. Once it does get running, it runs perfectly, so I'm at a loss. Any idea what's going on and what I can do about it?

Welcome to the Forum.
Could be a failing HD. Insert your installation disc and restart holding down the 'C' key. Once booted up, open Disk Utility from the options menu and run verify disk. See if that gives you any indication.

Trouble booting, tried several things, need help

I was using my iBook one day and put it into sleep mode and then put it in my bag. when i got home(less than 20 min later) it was off. I turned it back on and it was running fine. Then when ipicked it up off the kitchen table and walked over to the desk to set it down it just turned off. I turned it back on and the wheel froze part way through the boot. I held the power button to turn it off. This time it wouldnt turn on. I tried the reset PMU thing and still no luck. I got frustrated after several attempts and just left it alone for a week or so. I tried again one and it turned on so I booted it up in safe mode and it was working again. Then i went and shut it down. Just now it wont even turn on again. Battery is fully charged too. Any help would be greatly appreciated. Thanks in advance.

You could have them look at it at the Genius Bar but if it does need a new logic board there are cheaper places to have it done. DT&T Computer Services in Fremont, CA is about 1/2 the price.

My new/used G5...trouble ack! help please

I bought a used powermac G5 single 1.8 3gRAM. I installed tiger and have been trying to run an audio app called Digital Performer 4.6, but there has been terrible cpu spikes. The DP forums suggest that the new 4.6 version has some troubles with tiger. So, I was trying to install panther on my hard drive so that I could boot up in panther and see if DP worked better in that OS.
The computer shut restarted. About 30 sec into the reboot, the apple in the screen switches so that a third of it is cut off and switched over to the left side of the remaining apple--meaning it freezes. Now I can't figure out how to get the disk drive open.
Here is the kicker: the computer was dropped by fedex in the process of shipping. The case of the computer is bent and the rivets along the bottom have popped. I ran a system test of the computer's internal parts and everything passed. I am waiting for fedex to send me the claim app so that their insurance can fund the $600 plus to get everything taken out and replaced in a new case.
I am worried that the present freeze is a result of the damage in shipment.
1. How do I get the disk out?
2. What would should I do to test the internal working condition of the computer in light of the dropped computer?

Well....of course I am going to take it in or get it fixed or excahanged or whatever. I called apple...and they kinda helped me. But not really. They said it could be this...or that...or that.
I just wanted to get alittle feedback from actual fellow mac users and see if they have had similiar experience and what it could be.
I'm just trying to learn as much as i can before I have to lug it all the way into apple. Information is power.
Anyone else with some real advice?

Trouble booting off fibre array

I am having trouble getting my Xserve to boot off my Promise Fibre array. I have done the following steps:
1. installed on the internal drive and can see the fibre slice mounted
2. I did a Carbon Copy Clone to the fibre partition
3. Selected the fibre partition as the boot drive and rebooted
The fibre partition is also present if i were to run the installer from dvd. I'm stumped on what i can do.
Here are the specs that i'm trying to make work:
OS: Mac OSX Server 10.6
CPU: 2 x 2.66 Xeon Xserve
Ram: 18Gb
Fibre Card: LSI7204EP /w 4Gb cable
Fibre Array: Promise 32-bay Array
Fibre Switch: Qlogic 2Gb
Any help would be appreciated.
Thank you,
Jason

Jason
AFAIK you can't install an OS (using the normal methods) or boot from a fibre attached RAID.
